Echo: hdf5: security update to 1.14.5+repack-3+e13

medium Tenable Cloud Security Plugin ID 458348

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - H5Z__filter_fletcher32 in H5Zfletcher32.c in HDF5 prior to 2.3.0 computes the data length to checksum by
 subtracting the 4-byte trailing checksum size from the input buffer size without checking that the buffer
 is at least 4 bytes, allowing a size_t underflow. This allows attackers to cause a denial of service
 (massively out-of-bounds read and application crash in H5_checksum_fletcher32) via a crafted HDF5 file
 with a Fletcher32-filtered chunk smaller than 4 bytes, triggered via H5Dread, e.g. by the h5ls or h5dump
 tools. (CVE-2026-19028)

Solution

Update the hdf5 library and its related packages to version 1.14.5+repack-3+e13 or later.
